The huge open-air concert to be held on the Felvonulási Square will be free thanks to the assistance of T-Mobil. The organizers reserve their right to keep the performer’s identity a secret right until the last minute. Looking back at the success of the event in the past few years, it can be compared to the open-air concerts of other large European cities, such as the concert of the Hyde Park in London. The aim is also similar: entertaining mass crowds.
